Arc spring

directed along this helical axis and the lever arm to the system center point

The wire of the arc spring is mainly subjected to torsional stress.

[3][4] An arc spring requires suitable support to transmit torque.

This results from the friction of the spring on the radial support and is an intended effect to achieve damping in the system.

In order to make optimum use of the available space, systems consisting of inner and outer arc springs are often used.

[6] The arc spring is suitable for static and quasi-static as well as dynamic applications.
